NITED STATES MATTHIAS N. FORNEY, OF N'EVV YORK, N. Y.-

RAILWAY SIGNALING APPARATUS..

SPECIFICATION forming part of Letters Patent No. 250,51'7,'dated December 6, 1981,

Application filed July 11,1881. (No model.)

To all fav/wm it may concern Beit known that I, MATTHIAS N. FORNEY, ofNew York, county of New York, State ot' New York, have invented or discovered a new and useful Improvement in Railway Signaling Apparatus; and l do hereby declare thefolloiving -to be afull, clear, concise, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which-like letters indicating like parts- Figure l, Sheet 1, is a plan view or diagram ofa single-track railway-crossing, and of my improved apparatus as applied thereto. Fig. 2, Sheet 2. is a View in elevation of the hornesignal apparatus, or the apparatus arranged at or near the crossing. Fig. 3 is a like View of one of the distant signals. Fig. 4t, by an outline end view of a locomotivecab, and frangible attachments thereon, and cross-section of track, illustrates one feature ot' invention, as presently to be described. Fig. 5 is a detached side view ot'one form of signal-shifting apparatns, suitable for the purposesiu view. Fig. 6, Sheet 3, is a horizontal sectional view, to an e11- larged scale, ofthe shifting apparatus employed at the home signal, the section being taken in the plane ofthe lines a," Fig. 7; and Fig. 7 is a vertical sectional View, approximately through the middle of the apparatus, but showing some devices on opposite sides of the plane of section.

In a separate application I have described and claimed a system otinterlocking disks or sectors, by the use of which to lock one movable part or appliance of a railway structure by the movement of another.

The presentapplication relates more particularly to a system ot crossing-signals in which the interlocking is effected by the use of disks or sectors, such as are referred to and claimed in said application.

In a crossingsuch as illustrated by the crossing tracks T T', it is important that there be between them and the crossing. The distant signals it isproposed to Work with wires in the usual way.

On Sheet 2 the home signal is represented at Fig. 2, and the distant signal at Fig. 3. The home signal consists of a double semaphorearm, A2, attached to a vertical shaft, B, the whole heilig supported by a quadruped frame, C2, resting on a bed-plate, D2.

The safety-signal may consist cfa vertical.

board or plate, E2, (shown iu dotted lines,)and placed at right angles to the danger-signal A2. Consequently, when the latter is at right angles toonelineoftrack, and indicates danger77 or stop to an engineer approaching thereon, the safety or line-clear signal is displayed to the other. On top ofthe cab, or in any suitable position, socketed castings d are placed. These carry what will be called sal'ety-staffsb. Holes are drilled through the castings and the statt's, and they are secured by a string or wire and seals, c o.

On the ends of the home semaphore A2 wooden arms R R are attached. These are so nrranged that in case an engine should pass this signal While displaying danger to the en gineer, one of the arms R R would break off the safety-statt' b, and as the engineer could not place and reseal another, the breaking ot a staff would be a tell-tale77 which Would show whether he had passed a signal at danger.7

The shaft B is turned by a Worm-gear, Q, and

crank T. The distant signals are operated by' sheaves S S and levers U U U. Wire ropes V V are Wound on these sheaves and connected with the distant signals. In Sheet 3 these parts are shown on a larger scale.

The interlocking gear is of the same. kind as that used in connection With the switch as described in the application above referred to, the only important difference being that four 1 pulleys or sheaves for the distant signals are used instead ot' one.

The shaft B has a circular disk, A, which engages with other disks, C C C G, attached to the sheaves S S S S. Each of the vertical disks hasaslotornotch,c,inits edge. AThesenotches in C C C G are so located that when the levers U U are thrown so that the signals are at danger, the notches c are opposite to the disk A, as shown in theleft side ot Fig. 7. Consequently, when all the levers are shifted to indicate IOC tached to the other end.

' fused or alarmed and will suddenly shilt them r a sufficient amount of time for the approaching danger,77 A and the shaft B can revolve freely. The disk A has also a notch, c, Fig. 6, in its edge, which is located in such a position that when it comes opposite to any one ot' t-hedisks C C C C the home safety-signal is displayed to the track with the signal ot' which that disk is connected. y

It will be seen that when the notch e comes opposite to a disk, G, the latter is tree to re volve, and that all the others are locked by the periphery ofthe disk A en tering the notches c in such other disks. As. soon as a disk, C, is moved from a position indicating danger its full periphery enters the notch c, and so locks the disk A, and consequently the home signal, and the latter is not unlocked until such disk C and the distant signal are again placed so as to indicate danger. It thus follows that no distant signal can be moved to indicate line clear 7 unless the home signal gives the same indication, and that no two distant signals can indicate line clear77 at the same time, and that the home signal can be moved only when all the distant signals are set at danger, and also that when vany line is cleared the home and distant signals of the other line are locked at dangen T2 T2 are spring-treadles, which engage with the notches ffff, to hold the sheaves and levers in either 0i' the two positions of danger7 or line clear.

It sometimes happens with an arrangement of signals ot' this kind that after they are placed so as to indicate line clear77 to one track the attendant will suddenly become conai'ter a train has passed the distant signal on one track, and thus admita train on the other track. To guard against this the home signal is arranged so as to be operated by a worm, Q', and a worm-gear wheel, Q Q, and a crank, T,Figs.2and 5. Withthisarrangement,ifasignal-man should give the signals of line clear77 to one track and a train should pass the distant signal, and he should then become confused and endeavor to change the signals, he must tirst put the distant signal which was at line clear 7 at danger,and then before he can put any other distant signal at line clear77 he must first move the home signal from one track to the other. To do this he must turn the crank a certain number of times, which would occupy train to pass if ruiming fast, or be stopped by the changing home signal it' running slow. At any rate while he is engaged in moving the home signal no other trains can be admitted.

The distant signal shown in Fig. 3 consists of a post, F, to which a shaft, G, which carries the semaphore II and safctysignal I, is attached. 0n the lower end of the shaft are two pulleys, J and K. The former has a chain or Wire rope wound on it, which passes oveI` another pulley, L, and has a weight, M, at-

This is for the purpose of pulling the signal so as to indicate dangerf The wire by which the signal is moved from the home signal to indicate line -elear77 is attached to the lower pulley, K.

N is a wooden arm attached to the shaft with an iron weight or anvil, O, on its outer end placed in a proper position to strike a torpedo attached to the side of the enginecab by a suitable support, P. The object of this is to attract the attention of the engineer in case he should inadvertently pass the signal when it is setat danger. When the shaft is turned so as to bring the line-clear signal in view the arm N is turned with it, so as not to come in contact with the torpedo.

Modifications in the forms of the devices may be made, provided the'combiuation and operation are substantially preserved-as, for example, any or all the disks may be flanged to a cup shape and the notches cut in the edges of such flanges, so that, the edges of the flanges playing in the notches, or the notches coming into line, locking and unlocking may be done in the manner Vset forth. Such devices are included within the terms disk and sect0r,77 J

as herein used; but it should also be stated that a sector having the necessary length of arc may take the place of any of the vertical disks described.

The sameapparatus may be used on a doubletrack crossing, and, with, say, three vertical disks and a proper spacing of the notches, may be applied to a single or double track junction. In fact,the number of vertical disks maybe varied from two upwardly, one for each of two conflicting lines, as the eXigencies of the case may require.

The trangible tell-tale and the detonating alarm herein described are not claimed herein, but will form the subject-matter of a separate application.

It will be observed that in the construction shown and described the peripheries of the interlockin g disks or sectors cross each other or are arranged in different planes, and in this, among other respects, differ from'the construetion shown and described in English PatentNo. 3,427 of 1869, which latter is hereby disclaimed.

I claim herein as my invention- In a signaling apparatus for railway-cross` ings, a notched disk or sectoren a rotary home signal shaft, arranged in one plane of motion, in combination with two or more rotary notched signal-actuati ng disks or sectors, arranged with their notched peripheries crossing or intersecting in other planes thenotched periphery of the iirst disk or sector, substantially' as set forth, whereby when the home signal is 'set for any one line clear the distant signal for that line will be unlocked andthe disks or sectors of all conflicting signals will he locked.

ln testimony whereof I have hereunto set my hand.
